able Fast Ethernet Hubs

Conventions

References in this manual to the 16/24 port stackable Fast

Ethernet Hubs are frequently written simply as “hub” or “hubs”

where the text applies to all models. Model names are normally

used only to differentiate between models where necessary.

Unless differentiated by model name, all information applies to all

models.

1 INTRODUCTION

This chapter introduces the 16/24 port stackable Fast Ethernet

Hubs, as well as giving some background information about the

technology of the hubs use.

Product Description

Ideal for establishing or enlarging a Fast Ethernet LAN work-

group, the Stackable Fast Ethernet Hub provides port density

options from 16 to 190. The hub is IEEE 802.3u compliant and

falls into the Class II Fast Ethernet hub type. The ports on the

hub are standard RJ-45 connectors for use with Category 5 UTP or

STP cabling.

The hubs in the series, available in 16-port and 24-port models,

can be stacked with up to four hubs in a stack. A stack of four 24-

port hubs gives a total of 96 Fast Ethernet ports. A 16/24 port

stackable Fast Ethernet Hubs stack operates as a Class II Fast

Ethernet repeater, allowing it to be linked to another Class II Fast

Ethernet stack in the same collision domain.

2 UNPACKING AND

SETUP

This chapter provides information on the unpacking and initial

installation of your hub stack.

Unpacking

Open the shipping cartons of your hub and carefully unpacks the

contents. The carton should contain the following items:

♦ One Fast Ethernet stackable hub

♦ One AC power cord, suitable for your area’s electrical

power connections

♦ One daisy-chain cable

♦ Four rubber feet to be used for shock cushioning

♦ Screws and two mounting brackets

♦ This User’s Guide

Inspect the hub and all accompanying items. If any item is dam-

aged or missing, report the problem immediately to your dealer.

Identifying External Components

This section identifies all the major external components of the

hub. Both the front and rear panels are shown, followed by a de-

scription of each panel feature. The indicator panel is described in

detail in the next chapter.

Front Panel

♦ LED Indicator Panel

Refer to the next chapter, Understanding Indicators, for de-

tailed information about each of the hub’s LED indicators.

♦ Twisted-Pair Ports

Use any of these ports to connect stations to the hub. The ports

are MDI-X ports, which means you can use ordinary straight-

through twisted-pair cable to connect the hub to PCs, worksta-

tions, or servers through these ports. If you need to connect to

another device with MDI-X ports such as another hub or an

Ethernet switch, you should use a crossover cable, or connect

using the Uplink port (described below). For more information

about crossover connection, see the Crossover Cables section.

♦ Uplink Ports

The Uplink port is an MDI port, which means you can connect

the hub (or hub stack) to another device with MDI-X ports us-

ing an ordinary straight-through cable, making a crossover ca-

ble unnecessary.

In 24-port model, port 12 and the Uplink-1 port, port 24 and

the Uplink-2 is really the same port, except that their pinouts

are different. Do not use both Port 12 and the Uplink-1

port, Port 24 and the Uplink-2 port at the same time.

In 16-port model, port 16 and the Uplink port, is really the

same port, except that their pinouts are different. Do not use

both Port 16 and the Uplink port at the same time.

♦ Module Slots

Used to install module options for 100BASE-FX connection.

♦ Daisy-Chain IN Port

When cascading a set of stackable Fast Ethernet hubs, this port

should be connected to the Daisy-Chain OUT port of the previ-

ous hub in the stack (usually placed immediately above it). A

cascade of four hubs can be created in this way. The first and

last hubs in the stack use only one of the daisy-chain ports,

while the others use both.

♦ Daisy-Chain OUT Port

Works in conjunction with the Daisy-Chain IN Port (see above).

Connect this port to the Daisy-Chain IN Port of the next hub in

the stack (usually placed immediately below it), using the en-

closed daisy-chain cable.

♦ AC Power Connector

For the power cord.

Installing the Hub

Installation

The site where you install the hub stack may greatly affect its per-

formance. When installing, consider the following pointers:

♦ Install the hub stack in a fairly cool and dry place.

See Appendix B, Specifications, for the acceptable

temperature and humidity operating ranges.

♦ Install the hub stack in a site free from strong elec-

tromagnetic field generators (such as motors),

vibration, dust, and direct exposure to sunlight.

♦ Leave at least 10cm of space at the front and rear of

the hub for ventilation.

♦ Install the hub on a sturdy, level surface that can

support its weight, or in an EIA standard-size equip-

ment rack. For information on rack installation, see

the next section, Rack Mounting.

When installing the hub stack on a level surface, attach the rubber

feet to the bottom of each device. The rubber feet cushion the hub

and protect the hub case from scratching.

Rack Mounting

The hub can be mounted in an EIA standard-size, 19-inch rack,

which can be placed in a wiring closet with other equipment. At-

tach the mounting brackets at the hub’s front panel (one on each

side), and secure them with the provided screws.

Then, use screws provided with the equipment rack to mount each

hub in the rack.

INDICATORS

Before connecting network devices to the hub, take a few minutes

to look over this section and familiarize you with the front panel

LED indicators of your stackable Fast Ethernet hub, depicted be-

low.

Hub State Indicators

♦ Power Indicator

This indicator lights green when the hub is receiving power;

otherwise, it is off.

♦ 100M Activity

This indicators indicate data packet on the respective 100Mbps

Fast Ethernet segments will blink green.

♦ 100M Collision

This indicators indicate data collisions on the respective

100Mbps Fast Ethernet segments of the hub. (If several hubs

are stacked or linked together, all of them should detect and

indicate the same collision, since collisions span the entire net-

work segment.) Whenever a collision is detected, the respective

COL indicator will briefly blink amber.

100BASE-FX Module Indicators

The FX Link/Rx, indicate a good link to a module installed.

Port State Indicators

There have provide state indicators for each of the twisted-pair

ports on the hub. Each port’s LED status indicators report the

port and indicator for link or receive status.

The following describes each indicator and the meaning of each

condition:

♦ 100M Link/Rx

This indicator green when the port is connected to a 100Mbps

Fast Ethernet station , If the station to which the hub is con-

nected is powered off, or if there is a problem with the link, the

LED will remain off. And the indicator blinking green when the

data will be received to all other connected ports.
